p(x) = 3x^{2}  - 1 \:  \:  \:  \:  \: p(  \frac{ - 1}{2})  \\  \\ p( \frac{ - 1}{2} ) = 3 \times ( \frac{ - 1}{2}) ^{2}  - 1 \\  \\  = 3 \times  \frac{1}{4}  - 1 \\

= 3 \times  \frac{1}{4} -  \frac{1}{1}  \\  \\  = l \: c \: m \: is \: 4 \\  \\

= 3 \times  \frac{1 - 1}{4}   \\  \\  = 3 \times  \frac{0}{4}  \\  \\  =  \frac{0}{4}

P(x) = 3x² - 1

P(-1/2) = 3 x ( -1/2 ) ² - 1

3 x 1/4 - 1
